Apparently, digital pre-loads of GTA V PS3 Version were opened
(more like hacked, since it's a console game and that shouldn't be
possbile). Although I never heard of 90% of these people, take a
look at the list:

"Rockstar Leeds are currently looking for a talented graphics
programmer to help bring our latest titles to the PC platform.
Working together with the other Rockstar studios, you will be
responsible for maintaining the studio’s uncompromising quality
bar, delivering the highest quality PC experience
possible."

The only Rockstar Games titles without PC Versions are Red
Dead Redemption, Midnight Club L.A. and GTA
V.
